In construction, one of the key components that play a crucial role in securing structures together is the wedge bolt. A wedge bolt is a type of fastener that provides a strong and secure connection between two or more structural elements. It is often used in applications where a high level of tension load is required to hold the components together. The key feature of the wedge bolt is its ability to create a tight fit by expanding inside the hole when tightened, ensuring a reliable and long-lasting connection.

The functionality of metal expansion nuts centers around the principle of mechanical expansion. Upon the application of torque, the screw or bolt is threaded into the nut, which, in turn, causes the nut to expand outward. This outward expansion presses the sides of the nut against the inner walls of the hole it occupies, creating a tight fit. The added friction and mechanical grip prevent the nut from loosening over time, even in dynamic conditions.

One of the most significant advantages of chemical anchor fasteners is their high load-bearing capacity. Unlike traditional mechanical anchors, which can be limited by the tensile and shear strength of the materials they penetrate, chemical anchors distribute loads more evenly across a larger surface area. This is particularly beneficial in applications where heavy loads are expected, such as in building facades, heavy machinery installations, or structural reinforcements.
